Speed = Distance / time 1 of 9 What is acceleration? Acceleration is how quickly velocity is changing. 2 of 9 What are 2 ways in which velocity can change? Speed or direction 3 of 9 In distance time graphs, the gradient = the what? Speed 4 of 9 In Velocity time graphs the gradient = the what? Acceleration 5 of 9 In DT graphs, the downhill sections mean what? The object is going back towards the starting point 6 of 9 In DT graphs, the flat sections represent what? Where it has stopped 7 of 9 In VT graphs, the curve represents a what? Change in acceleration 8 of 9 What is the formula for acceleration? Acceleration = Change in velocity / time taken 9 of 9
